This invention relates to the method and device for the treatment of hose, especially the treatment in which hose containing artificial filaments are delustered.

An object of the invention is the methodof treating hose in which a more even deluster of the hose is obtained. Another object of the invention is the provision of a simple and efiicient device for carrying out the method of delustering hose wherein an even deluster is given to the leg portion of the hose and the welt portion of the hose is protected in such a manner that blisters, streaks, uneven delustering, etc. are not formed therein. Other objects of the invention will appear fromthe following detailed description and drawing.

In the drawing wherein like reference numerals refer to the same or similar elements:

Figure 1 is a side elevation of the improved hose form having a shield attached thereto, which shield is shown in dotted lines in the position em-' ployed when placinghose on the form or removing hose from the form. a

Figure 2 is an end elevation in section, taken on the line 2-2 of Figure 1.

Figure 3 is a plan view of a part of the device partly in section, taken on the line 3-3 of Figure 1.

By employing this invention, any suitable number of hose, say, from '1 to 12, may be placed upon a form and submerged in a heated bath containing soaps, chemicals, etc. for the purpose of delustering, dyeing or setting the shape of the hose without injury or uneven treatment being given to the hose in such baths. In employing this invention, a larger latitude of temperatures of the bath is permitted and the very narrow limits of temperature which formerly had to be maintained in similar treatments is no longer necessary. By employing this invention, the bath may be raised even to a vigorous boiling without detriment to the hose being treated.

In that the temperature of the bath does not have to be regulated within such close limits as by prior methods, larger numbers of hose may be dyed per man per unit of time. Many hose may be submerged in the bath without the necessity of paying particular attention to the change in temperature thereof. Further, this invention prevents the formation of blisters on the welt of the hose due to excessive boiling and ebullition of the bath.

In accordance with my invention, in treating hose orlike articles in a heated bath, I place the articles on a form and protect by a relatively close 1935, Serial No. 11,519

fitting shield the open end of the articles. Fur- .ther, in accordance with my invention, I produce a form adapted for use in the delustering of hose and otherwise treating of hose in heated baths. The device, in general, comprises a form for re- 5 taining the hose and a pivoted shield adapted to surround three sides of the open end of the hose and to fit into relatively close relation thereto to protect the same from excessive boiling and ebullition, with the result that no blisters, streaks, etc. are formed.

This invention is applicable to the treatment of hose of any suitable material wherein said hose are treated in a heated bath of any description. Thus, the invention is applicable to the deluster 15 ing of hose formed of artificial filaments, to the dyeing of hose or to the setting of the stitch shape of the hose wherein heated baths and/or a bath containing chemicals are employed.

Although this invention is applicable to the treatment of hose formed of any type of yarn or to articles of similar nature to hose, it is of par-- ticular applicability to hose and like articles formed of yarns or filaments containing an organic derivative of cellulose which is plasticized or softened by heated baths and baths containing certain chemicals. The yarns and filaments may be formed of any suitable organic derivative of cellulose, for instance, the organic esters of cellulose and the cellulose ethers. Examples of the organic esters of cellulose are cellulose acetate, cellulose formate, cellulose propionate and cellulose butyrate, while examples of celluose ethers are ethy cellulose, methyl cellulose and benzyl cellulose.

As an aid in describing the invention, the same will be described with reference to the drawing. In the device shown in the drawing, there is provided a form I of any suitable metal, wood or composition for holding the article, which in the particular device shown is to be a womans stocking. The form I may be suitably braced by crossbraces 2 or the form may be made of a solid material. The form I is suitably attached at one end to a key member 3 by any suitable means, for instance, swedging, welding or by forming the same integral therewith, as shown at 4. A suitable lug 5 may be provided on the key 3, which lug is adapted to fit into the rotating form holding device of a hose treating device, not shown. The 50 ting hea ed bath apparatus.

on three sides, the bottom being left open.

On a suitable pin 6 driven through the key member 3 is hinged a shield 1 which is, in crosssectlon, of U-shape and comprises two depending arms 8 and a curved back portion 9 integral therewith. This shield is adapted to pivot upon the pin 6 such that it may be swung to the position shown in the dot-dash line in Figure 1 to enable the hose or other articles to be placed on or taken off the form. When, however, the hose. is inserted into the heated treating bath, the shield 1 is adapted to be placed over the open end of the article on the form I, as shown in solid line on Figure 1. A suitable stop member Ill may be provided on the key 3 to prevent the rotation of the shield I to a position such that it would bear on the articles on the form I and to hold the shield in close proximity thereto without hearing thereon.

Obviously many changes may be made in the a device shown in the drawing. For instance, in

place of a pin 6, the key 3 may be provided with stud shafts, or the key 3 may be formed integral with a shaft, running lengthwise of the container holding the heated bath, which shaft is employed to rotate the hose into the bath and up again into a vertical position, i. e. out of the bath. The

materials used in forming the various parts may and a pin peened over on the ends in passing through the base of the shield lugs. This shield is turned back while the hose or other article, which is to be delustered or otherwise treated, is being placed on the form and then brought back into position so as to cover the welt of the hose The hosiery form with shield in place is suspended in a heated bath, for instance, in delustering, a boiling soap solution, in a horizontal position. An object of the shield is to prevent excessive boiling and ebullition within the shield, which boiling and ebullition tends to form blisters which cannot be removed in the final boarding operation, and also tends to distort, streak and otherwise deform the welt of the hose.

It is to be understood that the foregoing detailed description and drawing is merely given by way of illustration and many alterations may be made therein without departing from the spirit of my invention.

Having described my invention, what I desire to secure by Letters Patent is:
